To all whom it may concern:

Be it known that I, TONY Nnnone, citizen of Russia, residing at Whiting.1n the county 7 of Lake and State of Indiana, haveinvented use incutting leather shoe-laces, or leather strips for other purposes.

The invention has for an a simple and inexpensive device of the kindstated which will cut the strip of uniform width and which will befurther characterized by case ofmanipulation and rapidity of operation.v r For further comprehension of the invention, and of the objects andadvantages thereof, reference will be hadto the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

Fig. l of the drawings is a plan view of a device embodying theinvention.

Fig. 2 is a transverse section on the line 22 of Fig; 1. 1

Fig. 3 18 a detall plan view of the sheet to be cut, as prepared forinsertion in the device.

As here shown my improved device'comprises a supporting table 10 whichis formed to present a pair of spaced slots 11 extending inwardly fromone side thereof, leaving a central prong 12 projecting between them,this prong preferably terminating short of the edge line of the table asshown, while the opposed side walls of the slots are preferably narrowedin toward one another at their outer end portions as at 11".

Extending inwardly from one side of the prong 12 is a notch or recess 13which opens into the slot, this recess accommodating a knife 1% whichcuts the strip of leather from the main body thereof. This knife as hereshown comprises a vertically disposed. blade whose cutting edge facestoward the outer end of the prong 12, and which is fixed at its upperend on a lever arm 15. This arm is fulcrumed at its inner end as at 1 6tothe prong 12 and is provided at its outer end with a handle 17 foradjustment.

The outer end of this arm 15 projects freely under a serrated'strap oryoke 18 object to provide whichextends transversely of the prong '12attheouter end thereof and is secured at its ends to the latter, themain body of the yoke beingparallel to the surface of the prong 12 andspaced. therefrom a sufiicient distance to permit of vertical movementof the arm 15 so as to bring a lug 19 into or out of engagement with theserrations 20 on the yoke, whereby the ar may be locked in adjusted.position. Upon the arnr15 at a point be tween the yoke 18 and knife 14,are a pairv of rollers21 whose axes are parallel to the arm and whichare adapted to rest on the prong 12. Themanner and use of my improveddevice is as follows: The sheet to be, cut into a strip, and which isindicated at 23, has a comparatively small opening 2 1 first cut in themiddle thereof and a short tongue 25 cut in the wall of the opening. Thearm 15 is then adjusted, by springing the outer end downward and movingit laterally until the lug registers with the correct serration on theyoke 18, to locate the knife 14; at a distance from the inner end ofthe'recess corresponding to the width of strip it is desired to cut. Thesheet is then placed in position onthe device, which is done by movingit longitudinally of the prong 12 with the latter extended through theopenin g. 2d, the outer end of the prong extending over the sheet, whilethe other parts of the table are under the sheet and support thelatter,the sheet being finally given a movement to enter the partthereof adjacent the tongue 25 into the notch 13, andthe knife 14 .intothe slit between the tongue 25 and the main body of the sheet.

The tongue 25 is then inserted upwardly through the recess 13 betweenthe inner end of the latter and the blade 14. The cutting of the stripis then effected by pulling on thistongue 25 and at the same time givingthe sheet a rotary movement, which is done by hand, on the table. 2

During this operation, as will be apparent, the knife 14 will sever.from the wall of the opening 24 a strip 30 of the proper width, theopening constantly enlarging as the operation proceeds. By adjusting thearm 15 the distance between the knife 14 andthe endof the recess 13,which forms a gauge, may be varied, with a consequent variation inthe-width of the strip cut.

As'indicated in Fig. 1 I prefer to arrange the table 10 to present anumber of these cutting devices or 'units spaced therealong,

- lows v the members forming the outer walls of the slots being in theform of fingers 10, the

fingers for each unit being spaced from those of the adjacent units asindicated. 7

It will be noted that with the arrangement of the cutter andguide,working outwardly from an opening in the centre of the mate'-rial, the knife 14L, which is approximately tangential to the opening 24in the material, points away from said opening so that no tendencyexists to out toward said opening and so sever the lace, while at thesame time the guide formed by the end slot 13 prevents the knife frommoving tangentially of the opening Ql intothe body of the material. Itwill he noted also that by inserting the pronged element 12 through theopening in the material, a single element acts to hold the materialagainst both vertical and "lateral 2O displacement.

Having thus described my invention h t I I claim as new and desire toprotect by Letserrated yoke fixed to the table and under which the armpasses, lugon the arm adapted to engage in any one of thevserra tions inthe saidyoke, a V v 2.
